title: [Continuous intracorporeal glucose measurement using enzyme electrodes].
abstract: An enzyme electrode (GOD, Pt-Ag/AgCl) is introduced for amperometric measurement of the intracorporal glucose concentration in the subcutaneous tissue. Changes of the glucose concentration in the peripheral blood (PG) were induced by glucose- respectively insulin-infusion in healthy dogs. PG was compared with values found by out means of a sensor implanted in the necks of the dogs (SG). The regression equation SG = 0.81 PG - 1.39 was calculated by analysing 62 steady state levels. The regression delta SG = 0.83 delta PG + 0.22 submitted for the deviation of the normoglycemic base-level. A sensibility loss of the sensor of about 10% appears after an implantation duration of 7.5 hours in medium. Conclusions for the further development of the sensors follows especially with the in vivo functions (biocompatibility, diminution, sterilisation).
